When a liquid sample containing particles passes through the light beam of the sensor, a portion of the light is blocked by the particles, causing a change in light intensity. The amount of blocked light is proportional to the size of the particles. Therefore, by measuring the intensity and frequency of the light blocked by the particles passing through the sensor, the size and quantity of the particles can be obtained.

Suitable for solid particle pollution detection of hydraulic oil, lubricating oil, transformer oil (insulation oil), turbine oil (turbine oil), gear oil, engine oil, aviation kerosene, water-based hydraulic oil and other fluids, as well as other transparent, homogeneous, non strong corrosive&strong volatile fluids.

It can be widely used in aerospace, transportation, ports, power, petroleum, chemical, metallurgical, mechanical, automotive manufacturing and other fields. Among them, some key equipment commonly used for particle counter monitoring in various fields are as follows:

1F

Firstly, it is necessary to determine the testing scenario, whether it is used online for on-site work or offline for laboratory analysis? Simply put, if there is a high demand for measurement results and it is often necessary to use a sampler to take samples from the site and bring them back to the laboratory for analysis, desktop instruments should generally be selected; If it is necessary to frequently change the testing location and conduct testing on different hydraulic systems, and the requirements for testing results are high, portable instruments should generally be selected; If the requirements for measurement results are not high, but continuous monitoring of the pollution control trend of fixed system oil or pipelines is needed, online instruments should generally be selected; If used for multiple experiments on hydraulic filters, it is best to choose a dedicated online particle counter.

Determine the viscosity of the oil being tested

When the viscosity of the oil to be tested is too high (such as wind turbine gear oil), the built-in metering pump/plunger pump of the portable particle counter is prone to introducing bubbles or insufficient volume during the extraction of the liquid sample, which may affect the detection results. Generally, a pressure chamber needs to be added, and different viscosities can be solved by adjusting different pressure values, or by combining heating or dilution methods to reduce viscosity; Ordinary online instruments (without built-in pumps) and desktop instruments (with built-in pressure chambers and air pumps) usually do not need to worry.
